A vehicle uses 1 1/8 gallons of gasoline to travel 13 ½ miles. At this rate, how many miles can the vehicle travel per gallon of gasoline?

b. an equilateral triangle inscribed in a circle

step-by-step explanation:

we are given the figure of two circles having a triangle inside.

now, we know that,

"when a figure is lying inside an another figure, then the outside figure is known as circumscribed figure and the figure lying inside is referred to as the inscribed figure".

as we see that, the circles are containing the triangle completely.

thus, the circles are the circumscribed figures and the triangle is the inscribed figure.

hence, we get, 'an equilateral triangle is inscribed in a circle'.

this may not be at all, but i use the same website you're using for school, and if i'm stuck doing one of these i try to look for it on the section.
